The era of free distribution of identity projects is indeed becoming increasingly scarce. Carefully examining Rays Labs' Passport design, people often misunderstand it as some kind of NFT product, but in fact it operates on a different logic—the core purpose is to perform fine-grained segmentation of users. Through the Passport mechanism, project teams can clearly distinguish different types of users and implement targeted operational strategies. This approach may seem simple on the surface, but it implicitly contains a new way of evaluating user value within the Web3 ecosystem. The age of free distribution is over, replaced by a more precise user identification and classification system.
